The implementation in commit 182fe790c9 ("Add ability to undo
renumbering of dives") looks perfectly reasonable, but it depends on an
implementation detail: it assumes that the keys of the QMap are returned
in the same order in which they were placed there. Which apparently isn't
the case for some version of Qt.
With this commit we simply remember both the old and the new number for
each dive and therefore the order in which they are processed doesn't
matter.

Add the functionality to undo/redo removing of dives from trips. The
code calling remove_dive_from_trip has moved to the UndoCommands class.

Expand the undo feature by storing a list of renumbered dives' ids
and numbers so that the original numbers can be restored if needed.

Adds the ability to undo shifting of dive times. The change is captured
at simplewidgets.cpp and an undo command is created.

Add the undocommands.cpp / undocommands.h files, which will hold a
collection of classes that will hold undo commands.
